A housing assembly 100 for an electronic device and an electronic device200 per se according to embodiments of the present disclosure will bedescribed with reference to FIGS. 1 to 4.

FIG. 1 illustrates the housing assembly 100 according to embodiments ofthe present disclosure, and the housing assembly 100 includes: a firsthousing 110, a second housing 120 and a reinforcing feature, such as areinforcing column 130.

Specifically, as illustrated in FIGS. 1 and 2, the first housing 110 andthe second housing 120 define a receptacle 111, a mainboard circuit, abattery 220 and other components of the electronic device can bearranged in the receptacle 111. As illustrated in FIGS. 1 and 3, atleast a part of the reinforcing column 130 is embedded in at least oneof the first housing 110 and the second housing 120. That is, thereinforcing column 130 can be completely embedded in the housingassembly 100, or can be partially embedded in the housing assembly 100and partially exposed outside the housing assembly 100. At least a partof the reinforcing column 130 can be embedded in the first housing 110,and the reinforcing column 130 can also be embedded in the secondhousing 120. Certainly, the reinforcing column 130 can be embedded inboth the first housing 110 and the second housing 120.

It should be noted that the housing assembly 100 has poor structuralstrength at a location of the receptacle 111. By providing at least oneof the first housing 110 and the second housing 120 with the reinforcingcolumn 130, structural strength of the first housing 110 or structuralstrength of the second housing 120 can be enhanced, thereby promotingthe structural strength of the housing assembly 100 and facilitating alightweight design of the electronic device.

In the housing assembly 100 for the electronic device according toembodiments of the present disclosure, by embedding the reinforcingcolumn 130 in at least one of the first housing 110 and the secondhousing 120, the structural strength of the first housing 110 or thestructural strength of the second housing 120 can be enhanced, therebypromoting the overall structural strength of the housing assembly 100,reinforcing bending resistance of the housing assembly 100, andfacilitating the lightweight design of the electronic device. Accordingto an embodiment, in order to arrange the reinforcing column 130conveniently and optimize a spatial layout in the receptacle 111, thereinforcing column 130 can extend along a length direction or a widthdirection of the receptacle 111. That is, the reinforcing column 130 canextend along the length direction (e.g. an up-down direction in FIG. 2)of the receptacle 111, and the reinforcing column 130 can also extendalong the width direction (e.g. a left-right direction in FIG. 2) of thereceptacle 111. For example, FIG. 2 illustrates that the reinforcingcolumn 130 extends along the length direction of the receptacle 111(e.g. the up-down direction in FIG. 2), such that the overall structuralstrength of the housing assembly 100 can be improved, and the bendingresistance of the housing assembly 100 can be enhanced. In an example ofthe present disclosure, a plurality of spaced reinforcing columns 130can be provided, so as to further improve the bending resistance of thehousing assembly 100.

For instance, in an example illustrated in FIG. 2, two reinforcingcolumns 130 can be provided, one reinforcing column 130 is close to afirst end of the receptacle 111, and the other reinforcing column 130 isclose to a second end of the receptacle 111. In other words, tworeinforcing columns 130 extend along the length direction (e.g. theup-down direction in FIG. 2) of the receptacle 111, one reinforcingcolumn 130 is located at a left side of the receptacle 111, and theother reinforcing column 130 is located at a right side of thereceptacle 111. That is one reinforcing column 130 is located at a leftside wall of the housing assembly 100 while the other reinforcing column130 is located at a right side wall of the housing assembly 100.

In an example of the present disclosure, as illustrated in FIG. 3, acontour line of a cross section of the reinforcing column 130 can be acircle, so as to embed the reinforcing column 130 in the first housing110 or the second housing 120 conveniently, meanwhile enhance structuralstrength of the reinforcing column 130 and improve the bendingresistance of the housing assembly 100. It should be noted that theshape of the contour line of the cross section of the reinforcing column130 is not limited thereto. For instance, in another example of thepresent disclosure, the contour line of the cross section of thereinforcing column 130 can be a polygon, such as a triangle, aquadrangle or a hexagon, so as to promote connection strength andconnection stability between the reinforcing column 130 and the firsthousing 110 or the second housing 120. That is the reinforcing columncan have a circular or polygonal cross section.

According to an example of the present disclosure, the first housing 110or the second housing 120 embedded with the reinforcing column 130 canbe an injection molded part. It could be understood that, when thereinforcing column 130 is embedded in the first housing 110, the firsthousing 110 can be an injection molded part. During injection molding ofthe first housing 110, the reinforcing column 130 can be placed in aninjection mold for the first housing 110, so as to embed the reinforcingcolumn 130 in the first housing 110 at the same time of injectionmolding of the first housing 110. Similarly, when the reinforcing column130 is embedded in the second housing 120, the second housing 120 can bean injection molded part. During injection molding of the second housing120, the reinforcing column 130 can be placed in an injection mold forthe second housing 120, so as to embed the reinforcing column 130 in thesecond housing 120 at the same time of injection molding of the secondhousing 120. Therefore, an assembly process for the reinforcing column130 and the first housing 110 or the second housing 120 can besimplified, thereby shortening a production cycle and saving productioncosts.

In an example of the present disclosure, the first housing 110 or thesecond housing 120 can be an aluminum-magnesium alloy piece or analuminum alloy piece, so as to enhance the structural strength of thehousing assembly 100. In order to further improve the structuralstrength of the housing assembly 100, in an example of the presentdisclosure, the reinforcing column 130 can be a stainless steel piece.

It should be noted that materials of the first housing 110, the secondhousing 120 and the reinforcing column 130 are not limited thereto, aslong as the structural strength of the housing assembly 100 can beimproved. For instance, in another example of the present disclosure,hardness of the reinforcing column 130 is greater than hardness of thefirst housing 110 or the second housing 120. In other words, when thefirst housing 110 is embedded with the reinforcing column 130, thehardness of the reinforcing column 130 is greater than the hardness ofthe first housing 110. When the second housing 120 is embedded with thereinforcing column 130, the hardness of the reinforcing column 130 isgreater than the hardness of the second housing 120.

FIG. 4 illustrates an electronic device 200 according to embodiments ofthe present disclosure, and the electronic device 200 includes the abovehousing assembly 100.

In the electronic device 200 according to embodiments of the presentdisclosure, by embedding the reinforcing column 130 in at least one ofthe first housing 110 and the second housing 120, the structuralstrength of the first housing 110 or the second housing 120 can beenhanced, thereby promoting the overall structural strength of thehousing assembly 100, improving the bending resistance of the housingassembly 100, and facilitating the lightweight design of the electronicdevice 200.

Itshould be noted that “the housing assembly” herein can include onecomponent or can refer to a part composed of a plurality of components;“the receptacle” herein can refer to a space area defined by onecomponent or refer to a space area defined by a plurality of components.

Additionally, the housing assembly 100 has poor structural strength atthe location of the receptacle 111. By providing the housing assembly100 with the reinforcing column 130, the structural strength of thehousing assembly 100 can be enhanced, thereby facilitating thelightweight design of the electronic device 200.

In the housing assembly 100 for the electronic device 200 according toembodiments of the present disclosure, by embedding the reinforcingcolumn 130 in the housing assembly 100, the overall structural strengthof the housing assembly 100 can be enhanced, thereby improving thebending resistance of the housing assembly 100, and facilitating thelightweight design of the electronic device 200.

The electronic device 200 to which the present disclosure is applicablewill be introduced by example of the mobile phone. It is worthunderstanding that the following description is only explanatory and isnot intended to limit the present disclosure particularly.

In embodiments of the present disclosure, the mobile phone can includethe housing assembly 100, a display unit 210, a radio-frequency circuit,a memory, an input unit, a wireless fidelity (Wi-Fi) module, a sensor,an audio-frequency circuit, a processor, a projecting unit, aphotographing unit, the battery 220 and the like.

As illustrated in FIGS. 1 to 3, the housing assembly 100 includes thefirst housing 110, the second housing 120 and two reinforcing columns130. The first housing 110 can serve as a rear cover (or called abattery cover) of the mobile phone, and the second housing 120 can be afront cover of the mobile phone. The first housing 110 and the secondhousing 120 define the receptacle 111, and the radio-frequency circuit,the memory, the input unit, the Wi-Fi module, the sensor, theaudio-frequency circuit, the processor, the projecting unit, thephotographing unit, the battery 220 and the like can be arranged in thereceptacle 111. As illustrated in FIG. 4, the display unit 210 can beembedded in a front face of the housing assembly 100.

As illustrated in FIGS. 1 and 3, the reinforcing column 130 is embeddedin the second housing 120. The reinforcing column 130 extends along thelength direction (e.g. the up-down direction in FIG. 2) of thereceptacle 111. The two reinforcing columns 130 each extend along thelength direction (e.g. the up-down direction in FIG. 2) of thereceptacle 111, one reinforcing column 130 is located at the left sideof the receptacle 111, and the other reinforcing column 130 is locatedat the right side of the receptacle 111. That is one reinforcing column130 is located at the left side wall of the housing assembly 100 whilethe other reinforcing column 130 is located at the right side wall ofthe housing assembly 100. The two reinforcing columns are arranged attwo sides of the battery, and axes of the two reinforcing columns areflush with a central axis of the battery. Thus, the overall structuralstrength of the housing assembly 100 can be improved, and the bendingresistance of the housing assembly 100 can be enhanced.

As illustrated in FIG. 3, the contour line of the cross section of thereinforcing column 130 can be circular, so as to embed the reinforcingcolumn 130 in the first housing 110 or the second housing 120conveniently, meanwhile enhance the structural strength of thereinforcing column 130 and improve the bending resistance of the housingassembly 100. The second housing 120 can be the injection molded part,and during the injection molding of the second housing 120, thereinforcing column 130 can be placed in the injection mold for thesecond housing 120, so as to embed the reinforcing column 130 in thesecond housing 120 at the same time of injection molding of the secondhousing 120. Further, the hardness of the reinforcing column 130 isgreater than the hardness of the first housing 110 or the second housing120.

The radio-frequency (RF) circuit can be used to receive and transmit asignal during information transmission and reception or during a call.Especially, when downlink information from a base station is received,the RF circuit sends the downlink information to the processor forprocessing, and additionally sends uplink data from the mobile phone tothe base station. Usually, the RF circuit includes but is not limited toan antenna, at least one amplifier, a transceiver, a coupler, a lownoise amplifier, a duplexer and etc. In addition, the RF circuit cancommunicate with the network and other devices via wirelesscommunication. The wireless communication can employ any communicationstandard or protocol, including but not limited to global system formobile communication (GSM), general packet radio service (GPRS), codedivision multiple access (CDMA), wideband code division multiple access(WCDMA), long term evolution (LTE), e-mail and short messaging service(SMS).

The memory can be used to store software programs and modules, and theprocessor runs various software applications in the mobile phone andperforms data processing by running the software programs and modulesstored in the memory. The memory can mainly include a program storagearea and a data storage area. The program storage area can store anoperating system, at least one application program required for afunction (such as a voice playback function, an image playback functionand etc.); the data storage area can store data (such as audio data,contacts and etc.) created according to the use of the mobile phone. Inaddition, the memory can include a high-speed random access memory, andcan also include a non-volatile memory, such as at least one diskstorage device and flash memory device, or include other volatile solidstate memory devices.

The input unit can be configured to receive incoming numbers orcharacter information, and generate a key signal related to usersettings and function control of the mobile phone. Specifically, theinput unit can include a touch panel and other input devices. The touchpanel, also known as a touch screen, can collect a touch operation madeby a user on or near the touch panel (for example, an operation made bythe user on the touch panel or near the touch panel by means of afinger, a touch pen or any other suitable object or accessory), anddrive the corresponding connection device according to a preset program.Optionally, the touch panel can include a touch detection device and atouch controller. The touch detection device is configured to detect atouch orientation of the user, detect a signal from the touch operation,and transmit the signal to the touch controller. The touch controller isconfigured to receive the touch signal from the touch detection device,convert it into contact coordinates and send the contact coordinates tothe processor and can be configured to receive and execute a commandfrom the processor. In addition, it is possible to touch the panel inresistive type, capacitive type, infrared type, face acoustic wave andother types. The input unit can include other input devices apart fromthe touch panel. Specifically, other input devices can include, but arenot limited to one or more of a physical keypad, a function key (e.g. avolume control button, a power button, etc.), a trackball, a mouse andan operating rod.

The display unit 210 is configured to display information input by orpresented to the user, and various menus of the mobile phone. Thedisplay unit 210 can include a display panel, and optionally, thedisplay panel can be configured in forms of a liquid crystal display(LCD), an organic light-emitting diode (OLED) and the like. Further, thetouch panel can overlay the display panel; when the touch panel detectsa touch operation on or near it, the touch operation is sent to theprocessor to determine which type the touch event belongs to, and thenthe processor provides corresponding visual output on the display panelaccording to the type of the touch event.

The location, which can be recognized by the user's eye in the displaypanel, besides the visual output, can serve as a “display area”described later. The touch panel and the display panel can be twoseparate components to achieve input and output functions of the mobilephone, or can be integrated to achieve the input and output functions ofthe mobile phone.

In addition, the mobile phone can also include at least one sensor, suchas an attitude sensor, a light sensor and other sensors.

Specifically, the attitude sensor can also be referred as a motionsensor, and as one of the motion sensors, a gravity sensor can beemployed. As for the gravity sensor, a cantilever displacement device ismade of an elastic-sensitive element, and an electrical contact isdriven by an energy-storage spring made of the elastic-sensitiveelement, so as to achieve the conversion of gravity changes intoelectrical signal changes.

As an alternative motion sensor, an accelerometer sensor can be used.The accelerometer sensor can detect the magnitude of acceleration in alldirections (generally in three axes), and detect the magnitude anddirection of the gravity at rest, and can be used for attitudeidentification of the mobile phone (such as horizontal and verticalscreen switch, related games, magnetometer attitude calibration), andvibration-recognition related functions (such as pedometer andpercussion).

In this mobile phone, the motion sensors listed above can be used as anelement for obtaining an “attitude parameter” described later, which isnot limited thereto, however. Other sensors capable of obtaining the“attitude parameter” fall into the protection scope of the presentdisclosure, for example, a gyroscope. The working principle and dataprocessing of the gyroscope can be similar to the related art, so thedetailed description thereof will be omitted to avoid redundancy.

In addition, in the embodiments of the present disclosure, a barometer,a hygrometer, thermometer, an infrared sensor and the like can be usedas a sensor, which is not described in detail.

The light sensor can include an ambient light sensor and a proximitysensor, in which the ambient light sensor can adjust brightness of thedisplay panel in accordance with the ambient light, and the proximitysensor can turn off the display panel and/or backlight when the mobilephone is moved to the ear.

The audio circuit, a loudspeaker and a microphone can provide an audiointerface between the user and the mobile phone. The audio circuit cantransmit an electrical signal converted from the received audio data tothe loudspeaker, and the loudspeaker converts the electrical signal intoan audio signal to be output. On the other hand, the microphone convertsthe audio signal collected into the electrical signal, the audio circuitreceives and converts the electrical signal into audio data, andtransmits the audio data to the processor. After processed by theprocessor, the audio data is sent to, for example, another mobile phonevia the RF circuit, or output to the memory for further processing.

Wi-Fi is a short distance wireless transmission technology, and themobile phone can help the user send and receive e-mails, browse websitesand access streaming media through the Wi-Fi module which provides theuser with wireless broadband access to the Internet.

The processor is a control center of the mobile phone, is connected tovarious parts of the mobile phone by means a variety of interfaces andlines, and performs various functions of the mobile phone and dataprocessing by running or executing software programs and/or modulesstored in the memory and by invoking the data stored in the memory, soas to monitor the mobile phone overall. In at least one embodiment, theprocessor can include one or more processing units; preferably, theprocessor can be integrated with an application processor and a modemprocessor, in which the application processor mainly handles theoperating system, the user interface and the application program, whilethe modem processor mainly deals with wireless communication.

It should be understood that the modem processor may not be integratedinto the processor.

Moreover, the processor can act as an implementing element of theprocessing unit, to perform the same or similar function as theprocessing unit.

The mobile phone further includes a power source (like the battery 220)for supplying power to various components.

Preferably, the power source can be logically connected to the processorthrough a power management system, so as to achieve the management ofcharging, discharging, and power consumption and other functions bymeans of the power management system. Although not illustrated, themobile phone can further include a Bluetooth module or the like, whichwill not be elaborated herein.
